A new study proposes detecting life in space by spotting patterns across many planets instead of focusing on one at a time。 If life spreads and changes planetary environments, it could leave behind statistical clues linking planets together。 These patterns may reveal life even when traditional biosignatures are unclear or misleading
A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea。 Now, researchers propose a bold twist: dark matter might not be a single particle at all, but a mix of two different types that must interact with each other to produce
Calling AI things like “smart” or saying it “knows” something might sound harmless, but it can quietly mislead people about what AI actually does。 A new study shows that news writers are more careful than expected, rarely using strongly human-like language。 When they do, it often falls on a spectrum—sometimes describing simple requirements, other t
A new chip design from UC San Diego could make data centers far more energy-efficient by rethinking how power is converted for GPUs。 By combining vibrating piezoelectric components with a clever circuit layout, the system overcomes limitations of traditional designs。 The prototype achieved impressive efficiency and delivered much more power than pr
A new analysis of the “Boltzmann brain” paradox suggests our memories and sense of reality could, in theory, be random illusions born from cosmic chaos。 By uncovering circular reasoning in how physicists think about time and entropy, the study raises fresh doubts about what we can truly know about the past
Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality。 New research suggests that spontaneous “collapse” processes—possibly linked to gravity—could subtly blur time itself。 This wouldn’t affect clocks we use today, but it reveals a hidden limit to how precise time can ever be
For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention。 A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks。 But new research is challenging that bold
A major discovery is reshaping how scientists think about catalysts。 Researchers have, for the first time, captured oxygen atoms moving through the interior of a catalyst—not just along its surface。 This reveals that the bulk material can actively participate in reactions, opening a new frontier in catalyst design
A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm。 After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare kilonova—the kind of collision that forges gold and uranium。 But just days later, the signal shifted, beha
A key protein involved in fat metabolism has been found to do more than scientists once thought。 Instead of just releasing fat, it helps maintain healthy fat tissue and balance in the body。 When it’s missing or disrupted, the results can be surprisingly harmful
